Abstract
The invention relates to a split nest type unilateral bolt fastener. A button head bolt control rod is arranged on the tail portion of a button head bolt. A nest is divided into a plurality of parts. A nest control rod is arranged on the tail portion of each nest part. The button head bolt and the nest are located and installed through the control rods and an installing disk. The installing disk penetrates into a corresponding location hole of the button head bolt control rod; the button head bolt penetrates through an installing hole through the button head bolt control rod; the multiple nest parts are installed in sequence through the nest control rod, and then the button head bolt is drawn back through the button head bolt control rod, so that a bolt head of the button head bolt tightly presses the nest on the inner side hole wall of the installing hole; the installing disk and the nest control rod are dismantled respectively; a fastening washer and a nut penetrate through the button head bolt control rod to be installed; the round bolt head of the button head bolt is tightly pressed on the outer surface of the head portion of the nest by means of threaded connection between the nut and the bolt, and the inner surface of the head portion of the nest is tightly pressed on the inner side surface of the installing hole. The split nest type unilateral bolt fastener can be used for realizing unilateral operation and completing connection and fastening of structural parts, and can also be used repeatedly.
Description
Technical field
The present invention relates to a kind of structural member that can be used for and connect the bolt fastener that carries out monolateral installation in fastening, belong to civil construction project, mechanical assembly technique field.
Background technique
Current in civil construction and mechanical erection field, structural member is connected to fastening installation requirements amount large.With regard to the bolt generally using at present, when member is implemented to connect terminal operation, staff needs simultaneously, in the operation of member both sides, in a side, to insert nut bolt, then at opposite side with instrument by nut screwing clamping.This method for fastening connection is simple in structure, easy to operate, carry, but be only applicable in opening section member, in some special occasions, such as closed cross-section member or inconvenient member in an other side operation being connected when fastening, just cannot use this conventional bolt and nut method for fastening connection.Such as: in steel-pipe construction and concrete filled steel tube, beam-column connection place, because Steel Cylindrical Column is closed section, can not operate on both sides, can only one-sided connection, therefore cannot adopt this conventional bolt and nut to connect fastening and carry out fastening installation.And on domestic market, there is no corresponding monolateral bolt product, published Patents or to bolt shank weaken too much or bolt head force bearing point very few, overseas market has similar products, but above-mentioned existing patent or product are all difficult to, at erection stage, bolt is applied to larger pretension to form frictional bolt joint, the comprehensive mechanical property of its carrying is unsatisfactory, in Anti-quake Architectural Structure Design application, is very limited.In addition, external similar products are expensive, are difficult to adopt in a large number at home.
Summary of the invention
The present invention is for avoiding the existing deficiency of above-mentioned prior art, provides a kind of split nesting type monolateral bolt fastener, realizes monolateral enforcement terminal operation, and improve the comprehensive mechanical property of bolt carrying, also can be as required, for convenience detach, reusable.
The monolateral bolt fastener of split nesting type that the present invention proposes, described device is by snap bolt 1a, snap bolt control lever 1b, nested parts 2a, some nested control lever 2b, mounting disc 3, pad 4 and nut 5 form, it is characterized in that: the nested hollow cylinder body structure being combined by several nested parts 2a, described snap bolt 1a afterbody arranges snap bolt control lever 1b, nested parts 2a afterbody arranges nested control lever 2b, the described nested snap bolt 1a outside that is placed on, snap bolt control lever 1b passes corresponding positioning hole in mounting disc 3 with nested control lever 2b, during use, first snap bolt control lever 1b is penetrated to corresponding positioning hole in mounting disc 3, then by snap bolt control lever 1b, snap bolt 1a is passed to mounting hole 8b, by nested control lever 2b, first nested parts 2a is passed to described mounting hole again, when inside first nested parts 2a arrives at mounting hole, regulate first nested parts 2a position that nested control lever 2b is penetrated to corresponding positioning hole in mounting disc 3, repeated the installation of residue nested parts, several nested parts be combined into one complete nested, then pass through snap bolt control lever 1b by snap bolt 1a pumpback, the bolt head of snap bolt 1a is pressed on inside mounting hole on hole wall nested, now pull down respectively mounting disc 3 and nested control lever 2b, fastening gasket 4 and nut 5 are installed through snap bolt control lever 1b, by nut 5, with being threaded of bolt head, the bolt head of snap bolt 1a is pressed on to nested head outer surface, nested head internal surface is pressed on mounting hole inner surface, the monolateral connection of implementation structure part and fastening.
In the present invention, while dismantling two connecting fastening components, first snap bolt control lever 1b is screwed in to snap bolt 1a afterbody, pull down nut 5 and pad 4, by snap bolt control lever 1b, snap bolt 1a is sent into mounting hole inner side, then successively nested control lever 2b is screwed in to each nested parts 2a relevant position, by nested control lever 2b, each nested parts 2a is pulled down one by one, finally take out snap bolt 1a, realize separation and the dismounting of two clamp structures.
The structural feature of the monolateral bolt fastener of the present invention is: be nestedly split into some nested parts, in installation process, install one by one, after installation some nested parts form one complete nested; In mounting disc, be processed with the positioning hole to each control lever, with the installation to each nested parts, position.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention only needs a side operation, just can complete the connection terminal operation of bolt;
2, to bolt shank part without weakening, greatly having improved it can bearing load;
3, between mounting hole and bolt, space is less, has effectively improved the Section Space utilization ratio of bolt, can dwindle aperture is installed under carrying condition on an equal basis, reduces the negative effect of mounting hole to structural member carrying, has good mechanical property;
4, after installation, bolt head is complete circumferential uniform stressed, and mechanical property is better;
The mechanical properties such as 5, after installation, nested head construction is simple, carrying is even, resistance to compression shearing resistance are better;
6, the present invention can realize for convenience detach, reusable.
